Abstract
An intelligent gas identification system and method of gas identification in a specific environment. The intelligent gas identification system has a sensor, a pulse power supply module, and a processing device in which a plurality of chemical matter characteristics signals is stored. When the sensor is disposed in the specific environment, the pulse power supply module sends a variable pulse-amplitude-modulated voltage to the sensor, so that the sensor outputs a signal to the processing device. The processing device compares the outgoing signal to the chemical matter characteristics signals to determine an identification result for the gas.
